Cao Zhawa has been planting trees for most of his life. He lives and works in the heart of Mu Us Sandyland,  an area in the southwest part of Inner Mongolia.
In 1958,  when he was just 16 years old,  Cao started planting trees. Cao’s trees now cover an area of more than 1. 3 million square meters. Cao’s forest is worth an estimated 10 million yuan and can produce 100, 000 kilograms oxygen,  enough to sustain a full-grown adult for nearly a year.
Mu Us Sandyland is one of the places in China most affected by erosion(侵蚀) and desertification. The amount of annual rainfall ranges from 150 to 300 millimeters,  while evaporation(蒸发) between 2, 000 and 3, 000 millimeters. Cao recalls that his growing-up was troubled by sandstorms. This was one of the factors that motivated Cao to join and stay on the tree-planting program.
Popularly known as the “Green Great Wall”,  the project,  which is set for completion in 2050,  would be a 4, 800-kilometer greenbelt of trees and shrubs(灌木) protecting the area from strong winds and preventing soil erosion. Since the start of the Three-North Shelter Forest Program,  millions of people have joined in and become a vital part of the plan.
However,  the tree-planters face a host of challenges,  with watering the most difficult among them. “When I was young,  the level of groundwater was high, ” said Cao,  “But with less rain,  the trees are hard to plant and keep alive. ”
Planting trees has also become harder for Cao as he ages. However,  he doesn’t want to leave the forest in the care of his children,  and he insists the land belong to the government. “When I die,  I just want to be buried under the trees, ” Cao said. “Then I will be with them forever. ”
